This disclosure relates generally to location-based services,

BACKGROUND

A mobile device may have an instant messaging (IM) program that allows a user of the mobile device to chat with another user over the Internet. The IM program can offer real-time (“live”) transmission of text from the mobile device to a device of the other user, and receive and display real-time text received from the other device. The IM program can have a peer-to-peer or server-client architecture for transmitting the text in real-time.

SUMMARY

Techniques for live location sharing are described. A first mobile device and a second mobile device can communicate with one another using an IM program. The first mobile device can receive a user input to share a location of the first mobile device in the IM program. Sharing the location can include causing the second mobile device to display a location of the first mobile device in an IM program user interface on the second mobile device. Duration of sharing the location can be user-configurable. The second mobile device may or may not share a location of the second device for display in the IM program executing on the first mobile device.

The features described in this specification can be implemented to achieve one or more advantages. Compared to conventional IM program, the features described in this specification can allow chatting users to share more information. A user may see, in a user interface of the IM program, where the user's chatting partner is located. Likewise, the chatting partner can see where the user is located. Such information can enhance user experience, and can make tasks such as scheduling a gathering at a location easier. A user's privacy is protected according to the user's own preference as to with whom to share a location, and for how long.

The details of one or more implementations of the subject matter are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION Exemplary Live Location Sharing

FIG. 1 is a diagram illustrating exemplary live location sharing. Mobile device 102 can communicate with mobile device 104 over communications network 110 using an IM program. The IM program can be hosted on a server to which mobile device 102 and mobile device 104 connect. Alternatively, each of mobile device 102 and mobile device 104 can host a separate copy of an IM program. A first user of mobile device 102 and a second user of mobile device 104 may chat (112A, 112B) with each other online using the IM program.

During the chat, mobile device 104 can display location sharing interface 114 in response to an input from the second user. Location sharing interface 114 allows the second user to enable location sharing. Location sharing can include allowing mobile device 102 to see a real-time location of mobile device 104 in the IM program. Allowing mobile device 102 to see the location of mobile device 104 can include allowing mobile device 102 to access the location through a server. The location can be stored on mobile device 104, or submitted by mobile device 104 to be stored on the server temporarily for duration of location sharing.

Mobile device 104 receives the input to enable location sharing. In response, mobile device 104 notifies mobile device 102 of the location sharing. Mobile device 102 acquires the location of mobile device 104. Mobile device 102 can display virtual map 116 in the IM program. Mobile device 102 can represent the real-time location of mobile device 104 using marker 118 in virtual map 116. Marker 118 can move in virtual map 116, corresponding to physical movement of mobile device 104.

Exemplary User Interface

FIGS. 2A-2D illustrate exemplary user interfaces for live location sharing. Each user interface can be a user interface of an IM program executing on either mobile device 102 or mobile device 104 of FIG. 1. For convenience, each user interface will be described in reference to mobile device 102.

FIG. 2A illustrates exemplary user interface 202 for initiating live location sharing. The live location sharing can be sharing a location of mobile device 102 with a device that is in communication with mobile device through an IM program. The sharing can be limited to the IM program, where the shared location is visible in an IM program on the other device.

User interface 202 can include settings user interface item 204. Settings user interface item 204 can have a label “details” or any other label indicating that a user can access detailed settings of the IM program. Upon receiving a user input in settings user interface item 204, mobile device 102 can display a list of settings. One of the settings can be location sharing user interface item 206. Location sharing user interface item 206 can include a virtual button that, when touched, can cause mobile device 102 to display location sharing user interface 208.

FIG. 2B illustrates exemplary location sharing user interface 208. Location sharing user interface 208 can include various user interface items for specifying when to share a location of mobile device 102 with another mobile device in an IM program. Location sharing user interface 208 can include virtual button 210 that, when selected, causes mobile device 102 to share location of mobile device 102 in an IM program for a first time period, e.g., one hour. Location sharing user interface 208 can include virtual button 212 that, when selected, causes mobile device 102 to share location of mobile device 102 in an IM program for a second time period, e.g., one day. Location sharing user interface 208 can include virtual button 214 that, when selected, causes mobile device 102 to share location of mobile device 102 in an IM program for a third time period, e.g., indefinitely. Location sharing user interface 208 can include virtual button 216 that, when selected, causes mobile device 102 to share location of mobile device 102 in an program with another device when mobile device 102 is in proximity with the other device and in communication with the other device. The proximity can be user defined, e.g., within a same country, within a same city, or within X miles or meters of one another.

FIG. 2C illustrates exemplary map user interface 218 of an IM program executing on mobile device 102. Mobile device 102 can display map user interface 218 upon receiving a user confirmation for sharing the location. Map user interface 218 can include marker 220 indicating a current location of mobile device 102, as can be visible in an IM program on another device that receives the shared location. Accordingly, a user of mobile device 102 can be aware of what a user of the other device sees.

FIG. 2D illustrates exemplary map user interface 222 of an IM program executing on mobile device 102. Mobile device 102 is in communication with another mobile device using the program. Mobile device 102 shared location of mobile device 102 with the other device. The other device, in return, shared location of that device with mobile device 102. Mobile device 102 can display map user interface 222 that includes a virtual map, marker 224 indicating a real-time location of mobile device 102, and marker 226 indicating the real-time location of the other device.

Exemplary System Components

FIG. 3 is a block diagram illustrating exemplary interaction between mobile devices and their respective servers for live location sharing. Mobile device 102 and mobile device 104 can communicate with one another using communication channel 302. Communication channel 302 can be a communication channel for IM programs and can be based on a first telephone number PN1 of mobile device 102 and a second telephone number PN2 of mobile device 104. Mobile device 102 has logged into a user account on first server 304. The user account is associated with an account identifier ID1, e.g., an account name. Mobile device 104 has logged into a user account on second server 306. The user account is associated with an account identifier ID2.

Mobile device 102 received a user input requesting mobile device 102 to share a location of mobile device 102 with mobile device 104 in the IM program. In response, mobile device 102 can submit request 308 to server 304 requesting server 304 to provide location sharing information for passing to mobile device 104 through communication channel 302. In response, server 304 can provide mapping packet 310A to mobile device 102. Mapping packet 310A can include PN1 and ID1, and information on how long the location will be shared.

Mobile device 102 can submit mapping packet 310B, which can be the same as mapping packet 310A, to mobile device 104 through communication channel 302. Mobile device 104 provides the mapping packet 310B to server 306 as request 310C. Server 306 may already store the second telephone number PN2 of mobile device 104 and account identifier ID2.

Server 306 can submit the number PN1 and ID1 to an identity service (IDS) 312. The IDS 312 can include one or more computers configured to determine, based on PN1 and ID1, whether mobile device 102 is still logged in to server 304. The IDS 312 can send token 314 to server 306. Server 306 can submit token 314 to server 304. Server 304 can retrieve location of mobile device 102 and provide the location to server 306. Server 306 can, in turn, provide the location to mobile device 104 for displaying in the IM program.

FIG. 4 is a block diagram illustrating components of an exemplary server and an exemplary mobile device for live location sharing. The server can be either server 304 or server 306 (of FIG. 3).

Location subsystem 412 can provide the location to server communication subsystem 410 for submitting to the server for sharing.

Exemplary Procedures

FIG. 5 is a flowchart of an exemplary process 500 of live location sharing. A first mobile device, e.g., mobile device 102, can submit (502) a notification to a second mobile device, e.g., mobile device 104, through an instant message program. The notification can indicate that the first mobile device shall provide a first location of the first mobile device for sharing with the second mobile device. At time of submitting the notification, the first mobile device and the second mobile device can be in communication through the instant message program. The communication can be established based on a phone number of the first mobile device and a phone number of the second mobile device.

The first mobile device can receive (504), through the instant message program and from the second mobile device, a response to the notification. The response can be triggered by the notification. The response can be approved by a user of the second mobile device. The response can indicate that the second mobile device shall provide a second location of the second mobile device for sharing with the first mobile device.

The first mobile device can obtain (506) from a server, the second location. The first mobile device can then provide (508) a marker representing the second location for display on a virtual map in the instant message program on the first mobile device. Likewise, the second mobile device can provide a marker representing the first location of the first mobile device for display on a virtual map in an instant message program on the second mobile device.

The first mobile device can obtain, from the server, one or more updates of the second location. The updates can correspond to a movement of the second mobile device. The first mobile device can provide a representation of updated second location for display in the instant message program on the first mobile device. The representation of the updated second location can indicate a path of the movement.

FIG. 6 is a flowchart of an exemplary process 600 of live location sharing. An instant message program executing on first mobile device, e.g., mobile device 102, can receive (602) a notification to a second mobile device, e.g., mobile device 104. The notification can indicate that the second mobile device shares a location of the second mobile device with the first mobile device. The notification can include a mapping packet including a phone number of the second mobile device and an account identifier of the second mobile device.

The first mobile device can submit (604) and to a server, the mapping packet including the phone number and the account identifier for retrieving the location of the second mobile device.

Upon successful authentication by the server indicating that the second mobile device is logged in and that a location of the second mobile device is available, the first mobile device can receive (606) the location from the server during a time period as specified by the second device for sharing the location. The time period can be an hour, a day, or an indefinite time period as specified by the second mobile device according to a user input in the instant message program.

The first mobile device then provides (608) a marker representing the location for display on a virtual map in the instant message program on the first mobile device. During the time period, the first mobile device can provide the marker representing the location of the second mobile device for display in one or more other programs for displaying locations. The programs can include, for example, a “find my friend” application program.

FIG. 7 is a flowchart of an exemplary process 700 of live location sharing. A first server, e.g., server 304 of FIG. 3 can receive (702) a mapping packet from an instant message program of a first mobile device, e.g., mobile device 102. The mapping packet can include a phone number of a second mobile device, e.g., mobile device 104. The mapping packet can include an account identifier of the second mobile device. The mapping packet can indicate that the second mobile device has shared a location of the second mobile device with the first mobile device in the instant message program. The first server can be connected to the first mobile device by a communications network. The second server can be connected to the second mobile device by the communications network. The first mobile device and the second mobile device can be connected to one another by the same communications network or a different communications network.

The first server can submit (704) the phone number and the account identifier to an identity service for determining whether the second mobile device is logged into the account on a second server. The identity service can provide a token indicating that the second mobile device is logged into the account.

Upon receiving the token from the identity service, the first server can submit (706) a request to the second server for retrieving a current location of the second mobile device. The request can include the account identifier of the second mobile device. The current location of the second mobile device can be received by the second server from the second mobile device in response to an input on the second mobile device indicating that the second mobile device shares location of the second mobile device with the first mobile device.

Upon receiving the current location from the second server, the first server can submit (708) the current location to the first mobile device for display in the instant message program.

Exemplary Mobile Device Architecture

FIG. 8 is a block diagram of an exemplary architecture 800 for the mobile devices of FIGS. 1-7. A mobile device (e.g., mobile device 102) can include memory interface 802, one or more data processors, image processors and/or processors 804, and peripherals interface 806. Memory interface 802, one or more processors 804 and/or peripherals interface 806 can be separate components or can be integrated in one or more integrated circuits. Processors 804 can include application processors, baseband processors, and wireless processors. The various components in mobile device 102, for example, can be coupled by one or more communication buses or signal lines.

Sensors, devices, and subsystems can be coupled to peripherals interface 806 to facilitate multiple functionalities. For example, motion sensor 810, light sensor 812, and proximity sensor 814 can be coupled to peripherals interface 806 to facilitate orientation, lighting, and proximity functions of the mobile device. Location processor 815 (e.g., GPS receiver) can be connected to peripherals interface 806 to provide geopositioning. Electronic magnetometer 816 (e.g., an integrated circuit chip) can also be connected to peripherals interface 806 to provide data that can be used to determine the direction of magnetic North. Thus, electronic magnetometer 816 can be used as an electronic compass. Motion sensor 810 can include one or more accelerometers configured to determine change of speed and direction of movement of the mobile device. Barometer 818 can include one or more devices connected to peripherals interface 806 and configured to measure pressure of atmosphere around the mobile device.

Camera subsystem 820 and an optical sensor 822, e.g., a charged coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) optical sensor, can be utilized to facilitate camera functions, such as recording photographs and video clips.

Communication functions can be facilitated through one or more wireless communication subsystems 824, which can include radio frequency receivers and transmitters and/or optical (e.g., infrared) receivers and transmitters. The specific design and implementation of the communication subsystem 824 can depend on the communication network(s) over which a mobile device is intended to operate. For example, a mobile device can include communication subsystems 824 designed to operate over a GSM network, a CPRS network, an EDGE network, a Wi-Fi™ or WiMax™ network, and a Bluetooth™ network. In particular, the wireless communication subsystems 824 can include hosting protocols such that the mobile device can be configured as a base station for other wireless devices.

I/O subsystem 840 can include touch surface controller 842 and/or other input controller(s) 844. Touch surface controller 842 can be coupled to a touch surface 846 or pad. Touch surface 846 and touch surface controller 842 can, for example, detect contact and movement or break thereof using any of a plurality of touch sensitivity technologies, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch surface 846. Touch surface 846 can include, for example, a touch screen.

Other input controller(s) 844 can be coupled to other input/control devices 848, such as one or more buttons, rocker switches, thumb-wheel, infrared port, USB port, and/or a pointer device such as a stylus. The one or more buttons (not shown) can include an up/down button for volume control of speaker 828 and/or microphone 830.

In one implementation, a pressing of the button for a first duration may disengage a lock of the touch surface 846; and a pressing of the button for a second duration that is longer than the first duration may turn power to mobile device 102 on or off. The user may be able to customize a functionality of one or more of the buttons. The touch surface 846 can, for example, also be used to implement virtual or soft buttons and/or a keyboard.

In some implementations, mobile device 102 can present recorded audio and/or video files, such as MP3, AAC, and MPEG files. In some implementations, mobile device 102 can include the functionality of an MP3 player. Mobile device 102 may, therefore, include a pin connector that is compatible with the MP3 player. Other input/output and control devices can also be used.

Memory interface 802 can be coupled to memory 850. Memory 850 can include high-speed random access memory and/or non-volatile memory, such as one or more magnetic disk storage devices, one or more optical storage devices, and/or flash memory (e.g., NAND, NOR). Memory 850 can store operating system 852, such as Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks. Operating system 852 may include instructions for handling basic system services and for performing hardware dependent tasks. In some implementations, operating system 852 can include a kernel (e.g., UNIX kernel)

Memory 850 may also store communication instructions 854 to facilitate communicating with one or more additional devices, one or more computers and/or one or more servers. Memory 850 may include graphical user interface instructions 856 to facilitate graphic user interface processing; sensor processing instructions 858 to facilitate sensor-related processing and functions; phone instructions 860 to facilitate phone-related processes and functions; electronic messaging instructions 862 to facilitate electronic-messaging related processes and functions; web browsing instructions 864 to facilitate web browsing-related processes and functions; media processing instructions 866 to facilitate media processing-related processes and functions; GPS/Navigation instructions 868 to facilitate GPS and navigation-related processes and instructions; camera instructions 870 to facilitate camera-related processes and functions; magnetometer data 872 and calibration instructions 874 to facilitate magnetometer calibration. The memory 850 may also store other software instructions (not shown), such as security instructions, web video instructions to facilitate web video-related processes and functions, and/or web shopping instructions to facilitate web shopping-related processes and functions. In sonic implementations, the media processing instructions 866 are divided into audio processing instructions and video processing instructions to facilitate audio processing-related processes and functions and video processing-related processes and functions, respectively. An activation record and international Mobile Equipment Identity (MEI) or similar hardware identifier can also be stored in memory 850. Memory 850 can store live location sharing instructions 876 that, when executed, can cause processor 804 to perform operations of live location sharing, e.g., procedures as described in reference to FIG. 5 and FIG. 6.

Each of the above identified instructions and applications can correspond to a set of instructions for performing one or more functions described above. These instructions need not be implemented as separate software programs, procedures, or modules. Memory 850 can include additional instructions or fewer instructions. Furthermore, various functions of the mobile device may be implemented in hardware and/or in software, including in one or more signal processing and/or application specific integrated circuits.

Exemplary Operating Environment

FIG. 9 is a block diagram of an exemplary network operating environment 900 for the mobile devices of FIGS. 1-7. Mobile devices 902 a and 902 b can, for example, communicate over one or more wired and/or wireless networks 910 in data communication. For example, a wireless network 912, e.g., a cellular network, can communicate with a wide area network (WAN) 914, such as the Internet, by use of a gateway 916. Likewise, an access device 918, such as an 802.11g wireless access point, can provide communication access to the wide area network 914. Each of mobile devices 902 a and 902 b can be mobile device 102 and mobile device 104, respectfully, configured to communicate with one another using an instant messaging program and to share a respective location in the instant messaging program.

In some implementations, both voice and data communications can be established over wireless network 912 and the access device 918. For example, mobile device 902 a can place and receive phone calls (e.g., using voice over Internet Protocol (VoIP) protocols), send and receive e-mail messages (e.g., using Post Office Protocol 3 (POP3)), and retrieve electronic documents and/or streams, such as web pages, photographs, and videos, over wireless network 912, gateway 916, and wide area network 914 (e.g., using Transmission Control Protocol/Internet Protocol (TCP/IP) or User Datagram Protocol (UDP)). Likewise, in some implementations, the mobile device 902 b can place and receive phone calls, send and receive e-mail messages, and retrieve electronic documents over the access device 918 and the wide area network 914. In some implementations, mobile device 902 a or 902 b can be physically connected to the access device 918 using one or more cables and the access device 918 can be a personal computer. In this configuration, mobile device 902 a or 902 b can be referred to as a “tethered” device.

Mobile devices 902 a and 902 b can also establish communications by other means. For example, wireless device 902 a can communicate with other wireless devices, e.g., other mobile devices, cell phones, etc., over the wireless network 912. Likewise, mobile devices 902 a and 902 b can establish peer-to-peer communications 920, e.g., a personal area network, by use of one or more communication subsystems, such as the Bluetooth™ communication devices. Other communication protocols and topologies can also be implemented.

The mobile device 902 a or 902 b can, for example, communicate with one or more services 930 and 940 over the one or more wired and/or wireless networks. For example, instant messaging services 930 can allow mobile devices 902 a and 902 b to communicate with one another using an instant messaging program. Location service 940 can provide the location and map data to mobile devices 902 a and 902 b for determining locations of mobile devices 902 a and 902 b.

Mobile device 902 a or 902 b can also access other data and content over the one or more wired and/or wireless networks. For example, content publishers, such as news sites, Really Simple Syndication (RSS) feeds, web sites, blogs, social networking sites, developer networks, etc., can be accessed by mobile device 902 a or 902 b. Such access can be provided by invocation of a web browsing function or application (e.g., a browser) in response to a user touching, for example, a Web object.

A number of implementations of the invention have been described. Nevertheless, it will be understood that various modifications can be made without departing from the spirit and scope of the invention.

Operating system 1014 can be multi-user, multiprocessing, multitasking, multithreading, real time, etc. Operating system 1014 performs basic tasks, including but not limited to: recognizing input from and providing output to devices 1006, 1008; keeping track and managing files and directories on computer-readable mediums 1012 (e.g,, memory or a storage device); controlling peripheral devices; and managing traffic on the one or more communication channels 1010. Network communications module 1016 includes various components for establishing and maintaining network connections (e.g,, software for implementing communication protocols, such as TCP/IP, HTTP, etc.).

Location sharing manager 1020 can include computer instructions that, when executed, cause processor 1002 to perform operations of location sharing, e.g., procedure 700 as described in reference to FIG. 7. Location manager 1030 can include computer instructions that, when executed, cause processor 1002 to provide location of mobile device and virtual maps to a mobile device. Identity service manager 1040 can include computer instructions that, when executed, cause processor 1002 to perform functions of identity services 312 as described in reference to FIG. 3.

Architecture 1000 can be implemented in a parallel processing or peer-to-peer infrastructure or on a single device with one or more processors. Software can include multiple software components or can be a single body of code.

The described features can be implemented advantageously in one or more computer programs that are executable on a programmable system including at least one programmable processor coupled to receive data and instructions from, and to transmit data and instructions to, a data storage system, at least one input device, and at least one output device. A computer program is a set of instructions that can be used, directly or indirectly, in a computer to perform a certain activity or bring about a certain result. A computer program can be written in any form of programming language (e.g., Objective-C, Java), including compiled or interpreted languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, a browser-based web application, or other unit suitable for use in a computing environment.

Suitable processors for the execution of a program of instructions include, by way of example, both general and special purpose microprocessors, and the sole processor or one of multiple processors or cores, of any kind of computer. Generally, a processor will receive instructions and data from a read-only memory or a random access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memories for storing instructions and data. Generally, a computer will also include, or be operatively coupled to communicate with, one or more mass storage devices for storing data files; such devices include magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including by way of example semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, ASICs (application-specific integrated circuits).

To provide for interaction with a user, the features can be implemented on a computer having a display device such as a CRT (cathode ray tube) or LCD (liquid crystal display) monitor or a retina display device for displaying information to the user. The computer can have a touch surface input device (e.g., a touch screen) or a keyboard and a pointing device such as a mouse or a trackball by which the user can provide input to the computer. The computer can have a voice input device for receiving voice commands from the user.

The features can be implemented in a computer system that includes a back-end component, such as a data server, or that includes a middleware component, such as an application server or an Internet server, or that includes a front-end component, such as a client computer having a graphical user interface or an Internet browser, or any combination of them. The components of the system can be connected by any form or medium of digital data communication such as a communication network. Examples of communication networks include, e.g., a LAN, a WAN, and the computers and networks forming the Internet.

The computing system can include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. In some embodiments, a server transmits data (e.g., an HTML page) to a client device (e,g., for purposes of displaying data to and receiving user input from a user interacting with the client device). Data generated at the client device (e.g., a result of the user interaction) can be received from the client device at the server.

A system of one or more computers can be configured to perform particular actions by virtue of having software, firmware, hardware, or a combination of them installed on the system that in operation causes or cause the system to perform the actions. One or more computer programs can be configured to perform particular actions by virtue of including instructions that, when executed by data processing apparatus, cause the apparatus to perform the actions.
